I'm an instructor who would like to point students to a help file that answers: "How do I view instructor comments on individual quiz questions?"

The blue comment box at the top says: "While grading your quiz, your instructor may leave comments for the whole quiz. You can view these comments on the Grades page and on the Submission Details page."
I'm pretty sure the help page addresses only instructor feedback for the WHOLE quiz -- not INDIVIDUAL questions. I've read it several times. (But if I'm missing something . . . can someone point that out? And thanks.)
